Broadly, it is an object of our inventioh' to 'provide an-easily removable: pin 'and socket fo'r same which can be fastened to a cutting 'table in any desired positiom More particularly; it is: ari object' of ou r inven tion toprovide an inexbensive soeke base and removable pin ifon sam'e for use om cutting tabls 10 which can-'1 be arranged ini predetermined rows and; distances for hold-in my? desirednumbers of layers'of:clothl stretched position for 'cuttih-ge Heretofo're; variouskin'dsbof/- expensive a1 complicated--'devicesuhatveebeen made for qholdi ng 1 multiple layers-'ofixcloth imposition upon 'cutting tables.

A 115% set of pins 20 are dzhen 'inserted in' to meme tudinal --bores- I5- -'-of socketmembers l 5? The length of the pins used is determined by the height of the layer of cloth to be spread upon the cutting table for cutting.

By providing the short bore H in the socket member l5, the longitudinal bore I6 may easily be cleaned by forcing air therethrough, or by any other desired means.

Socket members of different inside and outside diameter may be used with the same base by keeping the threaded end portion uniform; however, the transverse lines of holes drilled in the cutting table should be of the diameter of the socket members. Any desired number of transverse rows of socket members may be attached to the cuttin table, since the tops of the socket members are flush with the cutting table top and do not interfere with the spreading of the layers of cloth or the cutting. Pins are inserted only in the rows of socket members used and the rows of socket members used are determined by the length of the ply 01' layers of cloth to be laid.

The cloth is spread. insuperimposed relation until the desired number of layers is spread; the cloth being engaged on the pins, as is well known in the art, preparatory for the arrangement of patterns so thatv the ply or stack of goods can be cut simultaneously.

In Fig. 3, the modified pin is provided with a keyway 26 in the form of opposed grooves. In the event that the pin. should stick within the socket member when it is attempted to be removed, a simple key 21, as shown in Fig. 4, having legs 28 adapted to fit within the grooves 26, is used to aid in the removal of the pin. Of course, any other desired type of key and keyway may be used in place of that shown in the drawing;

The socket member and base may be made of one piece, but we believe it better practice from the manufacturing standpoint to produce the unit in its preferred form, as shown in Figs. 1 and 3, since, the same base can be used with different socket members.

Referring to Fig. 5, numeral 29 represents a base with countersunk holes for fastening to the underneath side of a cuttin table by screws 30 as shown. Base 29 has an interior threaded hole in its center to receive the exterior threaded portion 3| of the socket member 32 which has a longitudinal bore 33 and a short threaded portion 34 of a smaller diameter than bore 33 thus creating a shoulder 35 for receiving the base 36 of the removable pin 31 which has a small exterior threaded extension 38 adapted to screw into the threaded portion 34 of the socket member. A. longitudinal bore 40 of smaller diameter than bore 34 may be-used for cleaning purposes similar to bore IT.

The socket member 32 is inserted through a bored hole in the cutting table in the same manner as socket member l5 of Fig. 1, except that it may be adjusted to the thickness of the cutting table and fixed in position by lock nut 39. We prefer to have the top of the socket member 32 a fraction below the cutting table top, as shown in Fig. 5. This type of socket member may be used on cutting table of different thicknesses and adjusted accordingly.

In Fig. 6 another modified socket and base member is shown. The socket portion 4[ has an exterior spiral .portion and a series of stepped interior piece, the base portion 42 having a wide end 43 tapering toward the socket portion, as shown. A series of lugs 44 are formed upon the tapered portion of the base.

In attaching the socket and base member shown in Fig. 6, a hole of a lesser diameter than the spiral portion is drilled through the cutting table and the socket and base member is driven into this hole from the underneath side of the cutting ta le. The spiral portion makes its own thread along the interior of the drilled hole as it proceeds into the hole. When the base portion 42 is reached, the lugs 44 act as gripping members in the softer Wood. The socket is driven to the desired height by blows upon end 43. Of course,

. the length of the socket and base member used is determined by the thickness of the cutting table.

It is obvious that other changes and modifications may be made in some of the details of construction without departing from the general spirit of the invention, as set forth in the appended claims.

We claim:

I. A cloth holder for cutting tables of the character described, comprising a base, screw holes in said base, a socket member having a longitudinal bore through the greatest part of said socket member and a short bore of smaller diameter than said longitudinal bore creating a shoulder within said socket member, a pin longer than said socket member of the diameter of said longitudinal bore and adapted to fit within said longitudinal bore, said pin having a flat end and a pointed end, said flat end adapted to rest upon said shoulder within said socket member.

2. A cloth holder for cutting tables of the character described, comprising a base, screw holes in said base, an interiorly threaded hole disposed in the central portion of said base, creating a shoulder, said socket member having an exterior threaded extending portion adapted to fit within said threaded hole of said base and of greater diameter than said threaded hole, said socket member having a longitudinal bore through the greatest part and a short bore of smaller diameter than said longitudinal bore creating a shoulder within said socket member, a pin longer than said socket member of the diameter of said longitudinal bore and adapted to fit within said longitudinal bore, said pin having a flat end and a pointed end, a knurled portion adjacent said pointed end, said flat end adapted to rest upon said shoulder within said socket member.

3. A cloth holder for cutting tables of the character described, comprising a base, screw holes in said base, an interiorly threaded hole disposed in the central portion of said base, creating a shoulder, said socket member having an exterior threaded extending portion adapted to fit within said threaded hole of said base and of greater diameter than said threaded hole, said socketmember having a longitudinal bore through the greatest part and a short bore of smaller diameter than said longitudinal bore creating a shoulder within said socket member, a pin longer than said socket member of the diameter of said longitudinal bore and adapted to fit within said longitudinal bore, said pin having a flat end and a pointedend, a knurled portion adjacent said pointed end, said flat end adapted to rest upon said shoulder within said socket member, a keyway adjacent said knurled portion and a key adapted to fit within said keyway for aid in removing said pin from said socket member.

sion adapted to screw into said threaded bore of 10 said socket member.

5. A cloth holder for a cutting table of the character described comprising a base, screw holes in said base, a threaded adjustable socket member having a longitudinal bore, a threaded bore of smaller diameter than said longitudinal bore and another longitudinal bore of smaller diameter than said threaded bore, a removable pin adapted to fit within said first-named longitudinal bore, said pin having a threaded extension adapted to screw into said threaded bore of said socket member, and a lock nut for said threaded adjustable socket member.

6. A cloth holder for cutting tables of the character described comprising a base for a removable pin, said base having an external spiral portion and a tapered end portion, said end portion hav ing a series of lugs around the tapered portion, said base having a series of three stepped internal longitudinal bores of progressively smaller diameters, the central bore being threaded for receiving the threaded end of said removable JOSEPH HERMAN.
